iOS: If you've taken a bunch of photos that you'd like to share with the world but the only tool you have to edit and upload them with is your iPad, Snapseed is a feature-rich photo editor that makes it easy to crop, rotate, adjust, filter, and then share your photos on Twitter, Facebook, or Flickr.

Apple recently awarded Snapseed the honor of being iPad App of the Year, and it's fairly obvious why—there are desktop photo editors with fewer features than Snapseed, and even though its packed with options, they don't get lost in Snapseed's touch-interface. Cropping and rotating photos is simple and easy, and the app supports full-resolution JPG, TIFF, and RAW photos up to 16-megapixels (anything larger will be down-sampled, so beware DSLR-users.)

If you're in a hurry, you can use the app's Auto Adjust feature to correct colors and levels and prep the photo for others to see in a single click, but if you're the type who needs more control, you can manually adjust the white balance, saturation, and contrast. If you want to apply effects, you can use Snapseed to make your image a tilt-shift photo, apply a vintage sepia tone, or focus on the center while blurring the background to make the subject of your photo pop. Snapseed is $4.99 in the iTunes App Store, and worth the price if you love using your iPad but don't want to put it down just to tweak your photos before you post them to Facebook or Flickr.
